The University of B.C. update was well attended as er ( judging by ZOOM video of the hall ) and 71 participants on Zoom. Hard to guess out, not too important, lets say 100 people or so ?
The slide deck was probably a mostly generic "What I am doing , what we are doing" and maybe some pulled out, etc to focus it on DNA tinkering of all kinds to increase quality of life in humans from first principles. Dr. C. Strayed into other areas about state of the art 'whatever' maybe 1/3 of the hour, which is pretty much perfect I'd say with lots of good slides with named persons everywhere and many companies this work generated. Chat up about making a near Mastodon, for instance, Xeno transplant pig to human heart, etc.
A few questions where asked, and answered. George C. was the only person on the speakers end, no usual banter politeness, which is cool but you know it is a delay of sorts too. Solid technology of life stuff, not much about regulation or ethics, etc.
In the unlikely case you don't know the general notions, this URL might help:

Edits to target genome has has as many as 24K edits to the B.P. Generally, three passes have been executed to get to enough reach there was no point in a 4th kick at it.
When a touched up rerecorded session is made and the URL posted, I will add it as a note here.
